Postcard from the USA!

Today I got a cool postcard from the USA! It showcases National Security Agency, which is the USA's signals intelligence agency. It headquarters is located at Fort George G. Meade in the state of Maryland. The card was published by the NSA's Office of Public and Media Affairs and the card is available at the NSA's National Cryptologic Museum, which the sender visited. I really like cards related to the military or to intelligence! Thanks Jonathan!
